We found robust evidence supporting insertion of a silver alloy-coated catheter to reduce the risk of CAUTIs for up to 2 weeks in adult patients managed by short-term indwelling catheterization. We also found evidence supporting the insertion of an antibiotic-impregnated catheter for reduction of CAUTI risk for up to 7 days. There was insufficient evidence to determine whether regular use of an antimicrobial catheter reduces the risk of CAUTIs in adults managed with long-term indwelling catheterization. There was insufficient evidence to determine whether selection of a latex catheter, hydrogel-coated latex catheter, silicone-coated latex catheter, or all- silicone catheter influences CAUTI risk. Expert opinion suggests that selection of a smaller French-sized catheter reduces CAUTI risk, but evidence is lacking.
